BELL-BINGER.

Application filed September 30, 1919.

To all whom it may concern:

Be it known that I, LYNNE LA MUNYON, a citizen of the United States, anda resident of Shoshone, in the county of Lincoln and State of Idaho,have invented a new and Improved Bell-Ringer, of which the following isa full, clear, and exact description.

This invention relates to improvements in bell ringers, and moreparticularly to an improved construction and arrangement of strikingdevice which maybe utilized in connection with a bell, such as a firealarm, or may of course be used for various other purposes, an object ofthe invention being to provide a hammer which comprises a leaf springand to which an oscillating movement is imparted, which movement isaugmented by the structure of the hammer causing rapid and continuousvibrations of the free end of the hammer.

With these and other objects in view the invention consists in certainnovel features of construction, and combinations and arrangements ofparts, as will be more fully hereinafter described and pointed out inthe claims.

In the accompanying drawings- Figure 1 is a view partly in elevation andpartly in vertical section, the section being taken on the line 1-1 ofFig. 2; and

Fig. 2 is a view in horizontal section on the line 2-2 of Fig. 1.

1 represents my improved hammer which comprises a plurality of leafsprings of varying lengths, the center spring or leaf being longer thanthe others and carrying at its free end a head or striker 2. The end ofthe hammer 1 is fixed to an enlargement 3 at one end of a bell cranklever 1, the latter pivotally supported on a bracket 5 secured to a base6.

A. motor 7 which constitutes an electric motor is supported on the base6 and serves to drive a gear train 8, the latter transmitting motion toa drive shaft 9. A crank arm 10 on the shaft 9 is connected by a link 11with the bell crank lever 4 and the said crank 10 is of a lengthappreciably less than the length of the bell crank member so that itsrotary motion imparts an oscillating motion to the bell crank lever.

Specification of Letters Patent.

Patented May 11, 1920.

Serial No. 327,549.

This lever at projects through a slot 13 in one end of a hood or casing12 which incloses the motor and gearing andis connected to the base 6 inany approved manner. 14% represents a bell which is in the path ofmovement of the head or striker 2 so that when the lever l receives itsoscillating movement,

it imparts this movement to the hammer 1 and the latter by reason of thefact that it comprises a plurality of leaf springs augments themovement, increases the vibrations, and thereby gives a rapid and loudalarm when operated.

This device is particularly adapted for use as a fire alarm, but may ofcourse be used in connection with any alarm or signal device used. Thegear train 8 operates to cut down or reduce the speed imparted from themotor and any number and arrangement of gears may be used to accomplishthe purpose desired.

Various slight changes may be made in the general form and arrangementof parts described without departing from the invention, and hence I donot limit myself to the precise details set forth but consider myself atliberty to make such changes and alterations as fairly fall within thespirit and scope of the appended claims.

I claim:

1. A hammer of the character described, comprising a plurality ofsprings secured together at one end, said springs of different lengths,and a head or striker secured to the free end of the longest spring.

2. A hammer of the character described, comprising a plurality ofsprings of different lengths, the intermediate spring being longer thatthe others, and a head or striker on the free end of said intermediatespring.

3. The combination with a bell crank le LYNNE LA MUNYON.
